Secret Worlds: ice ruins west

Climb on top of the ruined building that has a set of spiky nails sticking out of its roof. You can reach it by bringing down the stalactite with a missile and then jumping onto it before moving through the ice tunnel to your left. Jump to the corner where the two walls with nails meet, above the hole in the ruined building's roof. You need to adjust your position towards the hole so you are standing on the actual surface of the roof, not the nails. Your jump target is the top of the building in front of you, but it has an invisible barrier in front of it which you will need to clear. Ghetto jump forwards off the nails to provide the height to clear this barrier and stand on top of the building. Now work your way around the scenery to leave the map (one way to do this is shown in the video).
